Your printer has a 2.4Ghz radio and thus can only connect to a 2.4Ghz broadcast. If you have a dual or tri-band router, and are using the same SSID name for all broadcasts 2.4/5gHz, the printer might have difficulty connecting. You can alleviate this by temporarily disabling the 5G broadcast, connecting the device then re-enabling 5G. This might not be your issue, but you'll have to let us know.
